I have discovered that the small spring on the clutch cable is not just to return the handle but more importantly to disengage the clutch lever from the bucking bar as the bucking bar is spinning and wears against the clutch lever if it is in contact with it...my bucking bar was mushrooming over on the outside and I was adjusting my clutch a lot (was lubed with grease)..I added the small spring and I did file down the mushrooming end of the bucking bar (which seemed soft) and heated it in a propane torch until blood red and dropped it in a glass of water (to hopefully temper it harder) and reinstalled...been a few runs and no more clutch adjusting...was it the spring or tempering? (the metal didn't seem to get harder on file test) and I really suspect the spring is reducing the bucking bar wear...the Chinese wouldn't include the spring if it wasn't needed for some purpose (anything to save a cent)...

I love the dog!!! He's going off road

As a newbie, your vids really give a sense of what's involved with these things in the 'real world'... thx much!

Your video and sound quality is amazing

I just put a normal 66cc on that same bike for my neighbor. i had to adjust and grease everything but it was the best bike walmart had for a motor. my neighbor has put about 500 miles on it and just had to replace the rear tire because it was bald. I had to open up the transfer ports with a dremel from bad casting. the motor broke 3 spokes even with the hub adapter. Welded the sprocket to the rim and no more issues. i plan on getting a friction drive for my full suspension bike soon. great job on the videos

Having built a few of these myself, I predicted everything you were going to say went wrong. Many of us have encountered each of these problems. I wish other build videos mentioned these things. You saved me time with your solutions! I just began a new build. Thank you for stopping me from sanding and epoxying the 1" hub adapter and hub! Hahaha, I was thinking the exact same thing. I didn't want to use a set screw because I figured I'd drill into the hub berrings, but I'm getting a little rub on the rear fork as well. Thank you for the tip about cutting the rag joint in half! I was going to trace out and cut /drill into a plumbing gasket or rubber door mat, but that is so much easier.

I really do love your channel. Very entertaining and informative. Thanks for all the help Hover!

Man I built my first bike after watching several of your vids. Now have built a second one. Thanks for all the great vids and info dude🤘

I loved what Red Green said about 2 stroke engines" you nearly have two strokes getting one started"

Been watching your channel for quite some time and thank you for sharing your passion! I get a lot from it! Regarding the clamp-on adapter, i also was struggling with that for quite some time but finally looks like something worked for me which was using JB weld original. But not in putty form... doing the two formula mix. I sanded down both surfaces, added a liberal amount to fill the space between the 1in hub and clamp, let it dry for 24 hours and with a heater fan blowing at it to dry faster. One tip i discovered by mistake is let the JB weld spread all around the hub and on the sides of the clamp for maximum contact area and holding power since it all forms into steel. I'm using the 44-tooth sprocket (49cc motor) so I'm not sure if it will be enough holding power for the torque the 56-tooth sprocket demands but will try soon. Also I used JB Weld to fill the gap where the chain tends to lock up (thanks to your tip on doing that with a business card)

Bro, bought that muffler, and 99 percent sure, a piece of weld tore up my cylinder head and piston. The top of the piston looked like it was used for target practice! I should have checked better, A piece was rolling around when I got it, and it came out, but the motors vibration must have loosened more. Bang the hell out of those pipes! Great job mentioning that!! All of you're videos are very informative and entertaining! Thanks! ...GARY (Newbie 1 year, 2 bikes.)

Just started watching your video so you may have done this but I've seen several YD100 motors with piston backwards you may want to check that. Love your channel btw

Shout out to the Red Green show. You channel is one of the most informative.

Sounds like it’s holding back some power, my grubee runs awesome without the muffler cap. Maybe try adjusting the needle position on your next ride. Great vid look forward to the next one

Just gotta say with all the craziness going on right now, watching some of these bike build videos is reassuring that things will return back to normal eventually! I'm hoping to get another kit and have my kids put together to keep them busy while school is out and pretty much everything is closed around where I live.

Glad it's working for you man 😎

Can't wait for the engine to arrive

Nice video. Thanks!

Great choice on that bendy exhaust! I use those on all my bikes they are fantastic

These are making me wanna get a bike and hit the trails, I’ve subscribed!

Use Rubber mat cut as the spacers between the Sprocket and the spokes and inside retainers, instead of the stock spacers from the Kit. It allows for a truer sprocket and different thickness of Rubber can be used to get the sprocket off set. Good build and well explained.

Great video

Thanks for the detailed new bike build. Unless a bicycle comes from a REPUTABLE bicycle shop most likely the build quality is defective. This goes for all bikes motorized or not. This is a safety issue. Stay Safe !

Red green show my favorite 😂🤘

I started using spray white lithium grease for the gears a year ago. You dont have to deal with the old grease buildup and possibly getting onto the clutch pads. Grease also tends to get flung off the gears and not even lube anything after a while.

The red green show saved my life

When your dog ran by your guys I thought it was sped up… then I realised you two were talking so it couldn’t of been. HOLY CRAP HES FAST

Feeling at home hearing Red Green in the background.

Just did another kit on my bike and did allot of what you did.I bought the CDHPower magnesium 6-spoke rims and when I put the 56t sprocket and the 6-spd gear cluster on,they both hit the frame.I used nuts from an old rim as spacers on the inside of the frame and adjusted both sides.I have a 1" hub adapter that crushed 2 rims between the spokes before it slipped enough to bend spokes.Rag joint went back on 50t rim.

It sounds good man

My favorite part is the reflector delete lol 😂 i do the same thing 😂

cool video...makes me want to order a kit... I have a 1 inch hub with the clamp on adapter. all I had to do was sand each half on the mating surfaces and its never moved...of course a bigger sprocket will put more leverage on the clamp but you could always drill the threads out and run a bolt all the way thru the clamp to get it extremely tight, in any case you want there to be a 1/16" gap in between the two halves

I ordered that same roadmaster bike and an Mootos Engine kit for my first Motorized Bike

haha red green. my old boss went to school with him and apparently he is just like that in real life and he always said "keep your stick on the ice". random fact: my old boss is a pinkerton lol

Few tips for any metal pieces that slip. Take thick grit sandpaper fold it as many times as needed and wrap it ard then tightly hit the blots .never had a problem since with anything I did it on. Idle pulleys anything to do with metal

You make these builds look easy! I just had the same thing happen with the chain hitting on my Roadmaster. I grabbed another wheel from a Schwinn to make it work but that’s a great tip to get the gear closer to the rim. I kind of wanted to try one of those flex exhausts but I can’t tell if they make the engine louder or quieter. Intrigued to see it on one of your bikes and your thoughts.

Don't you just love this motor it's ran pretty good for me it's over squared and you can definitely feel it it's awesome the power you can feel from this one compared to my 80s bone stock there is a big difference

I’m building this same exact bike without the YD100 (PK80) These engines fit so nicely on this bike as well - every other build I needed to do so much modding that made the mounting look unclean. I took off all the ‘branding’ as well but I have all this residue that is taking forever to take off with WD-40. I’m using a hub adapter too... I hope I don’t run into the chain issue like you had - I’m using a different one from CDH power tho - It looks to fit and spin perfectly, But I had to dremel out the sprocket holes larger to fit the screws through🤞🏻🤞🏻🤞🏻

I doubt you will see this since this video is older, but I think it would be worth a try to use some loctite 638 or 648 retaining compound when installing the hub adapters and give it 24 hours to cure. That stuff is ridiculously strong, and quite literally built to retain cylindrical parts.

LA HOVER; YOUR THE ONLY GUY ON KZfaq WHO SHITBAGS, AND RIDES THE HELL OUT OF THOSE BIKES, YOU'VE GOT A LOT OF NICE TRAILS AROUND YOUR AREA ASWELL, BEAUTIFUL SPOT AND BEAUTIFUL THING YOU GOT THERE MAN,! LOOKS LIKE FUN, YOU'RE A GOOD MAN (PERSON), AND THESE ARE GOOD VIDEOS AND BIOGRAPHY OF YOUR LIFE! KEEP UP THE GOOD WORK, I LIKE SEEING YOUR VIDEOS, THANKS FOR THE USEFUL THINGS I'VE LEARNED ABOUT MOTORIZED BIKES FROM YOUR VIDEOS, GOD BLESS YOU, BEST OF LUCK WITH THE FUTURE, AND TAKE CARE OF YOURSELF, IVE SEEN LL YOUR VIDEOS & THANKS FOR THE ENTERTAINMENT ITS GREAT. PEACE

What a good doggo

Something I like to use for tire liner to this day is aluminum window blinds works awesome

i just found my neighbor head was cracked down the middle. i'm surprised it was running. i wouldn't have thought to look for that if it wasnt for your video on your 49cc having a cracked head. i had a stock head laying around and milled it down for high compression. it has some get up and go now.

Hey guys, I miss-aliened a small section of audio at 25:50 - 26:10. I was basically just explaining how I modified the rag-joint washer to get the sprocket as close to the hub as possible without pulling on the spokes... Nothing you will likely ever have to do, but you can see it clearly in the video, just in case. Sorry about that little hiccup. Enjoy to video!

I'm thinking of trying the poopoo exhaust ,i ordered a small expansion chamber it was so bad I'm not going to use it, welds and mounting surface were shot , holes were punched so far off can't get a nut on the stud. Lesson learned, great videos and info.

That's some rough terrain!

Love the stuff your putting out. Bout to build my first, a yd100, wondering what your thoughts are on the rubber vibration motor mounts? I saw another video where they used them for a bit of a snugger fit to the frame. Would that be more beneficial for road cruising or trail riding?

If you want a good crankset I recommend ixf cranksets and going with a sealed bearing bb and going single speed on the crank, they're lighter and give you the option to run 2 sprockets but I only run 1 on the front and went to a single speed on the wheel and with a 16t on the wheel and a 32t on the crank it gives you more than enough to get the motor going

That dog was havin a blast. LMAO 27:40

Where did you get the bike holder that you were using when working on it. Great videos thanks.

Love hearing red green in the background

Hey buddy , I was wondering if clamping bits of frayed copper speaker wire in the hub adapter would work to grip. It works well on stripped bolts and spark plugs when ur in a pinch. I'm putting together my first 2 stroke zeda 100 kit

Also I just used the 6 bolt tp mount my wheel sprocket to the wheel where the disc break rotor would go but I hardened the bolts to make sure they could handle the torque and I know you can find hardened bolts for this purpose

Good narration, speak with confidence, the small spring on the clutch it to keep the cable from raveling. I hate 2 strokes been thru 12 in 4 years life expectancy 6-8 months or 2800 miles. Now into 4 strokes nothing but an agonizing motor of a different race.

Like your channel man. Can you tell me if the yd100 cylinder will fit on the stock 49cc kit? If not will the 66cc kit bolt on. I'm a motorcycle tech by trade but you seem to have done a lot of these kits and their isn't that much info doing google searches. I put one on a roadmaster walmart bike for my son but it's just the 49cc kit. Pretty sure the 66/80 cylinder will fit and then I will upgrade the exhaust and do some port cleanup once I get the bigger jug. Not looking for crazy power just a little more and little crisper throttle response. Thanks

i saw something that might work for bikes with tubes going to the handlebar stems, it was a U-bolt designed for mounting tv antennas

my chain clearance is terrible too and its hitting top of back wheel frame . maybe need to get rag join better . 1st build . 44 tooth . gunna try get it better today :(

Hey I got the same motorcycle transmission chain for the drive chain didn't use it yet for some reason the stock chain is holding up perfect little scary lol does it work good

what about a brass clamp on adapter? (I assume the one you had trouble with was aluminium?) Would a harder metal bear more torque?

I'm thinking about trying a hub adapter but ik they have spinning issues debating on talking to a machine shop to see if they can tig weld one on

oh man those Cup.n.Cone bearings are my worse nightmare from the 90s, designed to drive you totally insane.

does adding extra oil into the cylinder really work well?

Lolol get some Fishing Channel in during coffee.

Just finished watching brother another awesome video...i know you didn't gag down on it or nothing like that but in part throttle operations how does it compare to the seeutek and triple???

Is it worth the extra money to get the yd 100?

To get the hub clamp to work there is a way to do it by drilling two 1/4 (choose your size, mm or SAE) holes directly through the hub on both sides and not through the axle then carefully thread the holes you made in the hub with the matching tap. Drill two holes in the clamp slightly larger, unthreaded, counter sink the the holes in the clamp so not much is above the clamps metal edge, chamfer, use hardened Allen bolts, do not use stainless steal it is brittle, place a washer under the bolts before tightening use some oil on the threads and the bolts, Tighten the clamp first to about 10 foot lbs then tighten the allen bolts down then tighten the clamp to full strength then return to the allen bolts and make sure they are also at full strength. Don't use loc-tight yet until its used for about 30 days and then you can use loc-tight on all bolts.

My yd 100 came with a c clip for the piston in the crankcase so now the crank is seized, I didn’t even get it started yet I went about 10 feet and then it just locked up so now I’m going to have to try and fish and pry it out with a screw driver

What would you recomend for the most reliable 2 stroke i cant find any pk's

Reflektors could be disassembled from the Bike and you could still have the good effects. There are tires with hi-visible retroreflective stripes and adhesive foils and no breaking plastic things fall from your bike or ruin the spokes

Hilarious you watching red green he’s our Canadian man spokesman lol.

Could the small spring assist in tighter clutch discs lockup ? Havent seen these up close but when i do maybe itll be love @1st feel . Regardless of the headaches in the marginal quality dept im redy to go for it cause upgrades abundant and plentiful but also like the thought of the ktm but info seems scarce and wanna know more also everyone holds the firestorm80 T40 in favorable regards , will probably be my 1st in frame chain dr bike and will also get the 5.5cc head w lotsa cooling area w the kit . Aircooled will trouble me emotionally anyway even w extra large fins

I have a 1" hub adapter that i haven't used yet, but now i'm thinking i could have it welded, just need someone that can weld aluminum. Not sure how well that would work though. Though a couple beads could be used as a key if the weld beads are on the hub itself.. So if i can't weld the hub adapter on directly without damaging the hub, maybe i can get away with 6 beads that i can use as keys on the hub itself. Then i can just dremel out some very tight fitting "key holes/slots" on the hub adapter.

Question is do you prefer a triple 40 or the yd? Was thinking about getting a yd but can't modify with a high performance head. Is power any different?

I've got to say this is one of the best video's I've seen about these motorized bikes. Someone that really understands what's going on with these bikes. The only thing I was wondering is how close are these engines to 100cc are they? BTW like your dog.

where did you get the gear cluster tool? i need another one

did you grease the bevel gear? whats the video with the unboxing procedure for the motor ie what to grease

Red green show season 3 on was filmed in port carling Ontario. I live a couple hours south. The hat he wares is called a Tilley. Free information!!!

Can you post a link? There are alot of different sellers and I'd like to buy a good one that doesn't require a lot of modification just to get it installed and working as it should. Thank you for your time and assistance.

Six bolt pattern disk brake hub if frame is tight hub can be milled down!!!

What oil do you use

So how did you like the 56 tooth sprocket! Did it give you better acceleration?

Heads up on the throttle twist add on, you can remove the little notch they have in the twist so you don’t have to hammer a hole into the bars.

Should I spend the extra 20$ for the Zeda Bt 100

I just bought a 100cc motor off ebay for 75 dollars that looks to be a yd100 with a 2 piece cylinder/head top end. I'm hoping so because the head looks pretty big and has big fins. If so I'm thinking they make an Iron sleeve cylinder for 40 bucks.

I was going to ask you about southern custom cycles I was considering buying a engine kit from them

Good job on the build, but I sure hope you have better luck with this motor than I did. For a brief time the motor seemed plucky, but there were heat issues that I could never quite get to go away, as well as a whole host of other problems like 4-stroking, the piston eventually smashing into the connecting rod and the inside of the cylinder being discolored. By it's last run the motor could barely take the bike to 10MPH. Quite honestly the worst motor I've ever owned, clocked up very few miles before I took it off and replaced it with the cheapest kit on eBay - which rendered the purpose of the upgrade from the old bike kinda pointless. Here's hoping it was just a bad one and your one serves you much better.

on these stock carburetors, is there a small hole that goes from the float chamber to atmosphere? because mine always smells of petrol.

Rob at zeda actually has a video where shows he leaves out the outside rubber on the rag joint

On that hub adapter grind the ends down and it will get a lot tighter it won't bottom out...

Okay so it's been a minute since I've commented on this video I'm working with 2 yd 100 Motors two different builds completely structure wise but very similar both 29 and both have custom exhaust one has 36 tooth one has 44. I have a reed valve on one that I just redid the gaskets and got it all together now it runs like s*** I won't get too annoyed though s*** happens just a small carburetor issue these Kaioken clone carburetors are not bad if you can find the adjustment on them they're sort of a pain in the ass though I will say my stock carburetor that came with the yt-100 is running very good no issues on that one definitely can feel the difference in draw and latency between the two but not bad. I will say the 100 are a new breed were literally waiting for more parts and more things available to upgrade on these motors that's one thing I do love and miss about the 80s and I was always tell somebody you can't go wrong with an 80 as well they're great Motors several different good brands out there

Do they still make the Granite Peak?

I made the mistake of topping out my yd100 for some periods of time... destroyed the piston and cylinder... I put new piston and cylinder in and now it won’t start... could I have messed up anything else in the motor ? But I noticed when I took it apart out first one of the clips was missing a piece..

does Walmart still sell these ? i think i'll get one if they do

Do you ever use the mag wheels on your bikes ?

What kind of toque do you have, will it climb a 30 degree hill? I live in the foot hills of the NC mountains, so they are lots of 15,20, and even a few 30 degree hills.

i forgot to ask. how much of a different in performance gain between the typical 80cc and the YD100?

What sprocket did you use?

You ever thought of using a rear disc brake hub

Don’t you ever use spring chain tensioners?

When I didn’t have my small spring my cable screw kept loosing up from not having tension
